Moderate alcohol consumption and depression prevention: A critical review.

There is a clear consensus that alcohol use disorders are associated with poorer outcomes concerning depression, and that drinking alcohol shouldn`t be recommended because of the risk of dependence. Until recently, literature focused almost exclusively on patients with alcohol use disorders and excludes patients with moderate alcohol use (MAU). It’s has been shown that MAU can prevent or improve the evolution of chronic diseases such as cardiovascular diseases, but several researchers have suggested that there is no safe level of alcohol drinking due to other effects on health. Nevertheless, there is some evidence regarding the antidepressant effect of moderate alcohol consumption. This critical review aims to sum up the direction and tendency of current research on the effect of MAU on depression and relate the causal or confounders factors that might explain the results.
